First, the problem of the large-scale pig farm from the ingredients to pay attention to 1. Crude fiber: The external ternary crossbred pigs raised on large-scale pig farms are recognized as lean pigs. The crude fiber level of the diet should not be too high. Generally, the fattening pigs are 3%-4%, and the energy feed is mainly Corn, wheat bran, and protein feed are mainly prepared from raw materials with low crude fiber content such as soybean meal and fish meal. Do not use too much raw materials with high fiber content such as rice bran and rice. 2. Crude protein: The lean rate of pure external ternary crossbred pigs is generally above 60%, and the proportion of protein in lean meat tissue is high. We must give full play to the genetic potential of lean muscle pigs to synthesize muscle tissue, so in nutrition, it is necessary to provide enough crude protein through the diet. The lean protein pigs had a dietary protein level of 17.5% in the 15-30 kg body weight stage, 16.5% in the 30-60 kg body weight stage, and 15.0% in the 60 kg body weight. The nutrition of dietary protein is actually the nutrition of amino acids. The balance and supply of amino acids in lean-type pig diets is especially important. The actual feed preparation often requires the addition of lysine 0.1%-0.15% in the diet, methionine. 0.05% - 0.08%. 3. Nutritional balance: Large-scale pig farms have high density of pigs, and are kept away from the soil (usually cement floor), lacking sunlight and green feed, and fed with high protein and high energy nutrient levels, combined with lean meat. The growth rate of pigs is fast, and the daily weight gain is as high as 0.8 kg or more. Therefore, the concentration of vitamins, minerals and trace elements in the diet needs to be increased accordingly. Otherwise, an imbalance in the nutritional level of the diet can result in wastage or relative lack of certain nutrients in the feed. Many large-scale pig farms now recognize the many benefits of using concentrates and premixes from production practices. It is worth pointing out that some drugs that cause a small amount of poisoning, such as sodium selenite, olaquindox, etc., are difficult to achieve uniformity by self-mixing by manual mixing, and feed manufacturers can do this. . Second, the problem of the large-scale pig farm to buy materials to pay attention to 1. It depends on the technical strength of the feed manufacturer. High-quality feed is produced with high-quality raw materials, combined with scientific feed formula and advanced processing technology. The procurement and testing of high-quality raw materials, scientific feed formulation levels and advanced processing techniques are closely related to technological strength. Due to unscientific feed formula or improper processing technology, vitamin A deficiency causes the quality of boar semen to decrease, which directly affects the sow's litter rate and survival rate. 2, depends on the after-sales service of feed manufacturers. The after-sales service of the feed manufacturer is responsible for the pig-raising benefits of the feed they produce and the problems caused by the feed itself. Some manufacturers can also provide compulsory consultation and diagnosis for pig diseases caused by non-feed factors. For example, when the swine group has a toxoplasmosis, the manufacturer can produce feeds supplemented with sulfa drugs and pyrimethamine for the whole group to control the pigs; For pig farms with severe yellow and white piglets, some drugs can also be added to the feed of lactating sows as part of a comprehensive control of such diseases. 3, depends on the production effect of feed pigs. The quality of the purchased feed can be tested in the practice of pig production. High-quality feed Under good feeding and management conditions, the growth rate of pigs can reach the expected daily gain. The feed-to-weight ratio is maintained at a level of 2.8 to 3.2:1. It does not cause nutrient metabolism and toxic diseases in growing and finishing pigs. The pigs are not found to be sold due to residual drugs or illegal drugs; the feed for breeding pigs does not cause reproductive failure due to nutritional factors and certain toxins or drugs. In terms of pig breeding efficiency, it should be equal to or higher than the level of similar and same-scale pig farms. Third, pay attention to the correct use of The nutritional needs of the diet are different at different physiological stages of the pig. According to the characteristics of nutritional needs of pigs in various physiological stages, properly formulating diets or purchasing feeds, and raising them properly, can most effectively exert the production potential of lean pigs, and can maximize the economic benefits of large-scale pig farms. However, some large-scale pig farms use growing fattening pig feed to feed the breeding pigs, which may cause great harm. First, the vitamins in the growing fattening pigs do not meet the requirements of breeding pigs, such as various vitamin levels and the addition of biotin; the second is to grow fattening pigs for growth, adding high-copper, high-zinc and high-dose antibiotics. These substances may have adverse effects on the reproductive performance of breeding pigs; the third is to increase the cost of feed production in order to reduce the cost of feed production, with a certain proportion of cotton and rapeseed, while cotton and rapeseed are strictly prohibited in the breeding of pigs, otherwise it will be Lead to breeding disorders in breeding pigs. Breeding pigs must be purchased or self-contained with pig-specific materials. C&K MOSAIC , https://www.cnkmosaics.com
